Ordering Information

Cisco ASR 1000 series routers introduce the Cisco IOS XE software as their software architecture. Based on Cisco IOS software, Cisco IOS XE operating system is designed to provide modular packaging, feature velocity, and powerful resiliency. Because of the extreme flexibility and robust performance of ESPs based on Cisco QuantumFlow Processor technology, network security, deep packet inspection, firewall, and many other advanced features are implemented in the Cisco IOS XE operating system without the need of a service blade. One of the most innovative features is support for dual Cisco IOS software consolidated packages in a single route processor for software redundancy in the 2RU and 4RU chassis systems. This dual Cisco IOS consolidated package could be the same software consolidated package for backup or different software consolidated packages for resilient upgrade. Information about compatibility of supported dual software consolidated packages is available in the release notes. Note that with redundant hardware route processor and ESP configuration in the 6RU model, Cisco IOS software redundancy in a single route processor in a redundant 6RU system is not supported.
